Solution: Substance A is a nonpolar liquid and has only dispersion forces among its constituent particles. Substance B is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. When substance A and B are combined, they spontaneously mix.Why do the two substances mix?

Problem

Substance A is a nonpolar liquid and has only dispersion forces among its constituent particles. Substance B is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. When substance A and B are combined, they spontaneously mix.
